The role of axillary lymph node dissection in breast cancer patients with sentinel lymph node micrometastases.

AIM: To identify by means of clinical and histopathological features a subset of breast cancer patients with sentinel lymph-node (sN) micrometastases and metastatic disease confined only to the sN in order to spare them an unnecessary axillary lymph node dissection (ALND). MATERIALS AND METHODS: From January 1998 to December 2004, 116 patients with sN micrometastases underwent standard ALND for early-stage (T1-2 N0 M0) invasive breast cancer; clinical and histopathologic parameters were prospectively collected and evaluated by means of univariate and logistic regression analysis in order to identify which patients with sN micrometastases were free of metastasis in axillary non-sN. RESULTS: Sixteen of 116 patients with sN micrometastases had tumour involvement of non-sN, with six and 10 patients having non-sN micrometastases and macrometastases, respectively. None of 19 patients with primary tumour measuring </= 10 mm had tumour-positive non-sN; moreover, none of 15 patients with G1 tumours had non-sN metastases. The mean tumour size in patients with non-sN involvement was 21.3 mm (range, 12-40 mm). Univariate test of association between clinical and histopathologic features and non-sN status showed that the primary tumour size (P=0.005) and the presence of lymphovascular invasion (P=0.000) were the only significant predictors of non-sN involvement. By logistic regression, primary tumour size (P=0.011), lymphovascular invasion (P=0.001), and size of sN micrometastases were the only variables remaining into the model, although the latter parameter was not statistically significant. CONCLUSIONS: In patients with sN micrometastases, primary tumour size and lymphovascular invasion significantly predict non-sN status; notably, no patient with T1a-T1b and/or G1 tumours had non-sN metastases so that they could be spared an unnecessary ALND.

The prognostic role of the sentinel lymph node in clinically node-negative patients with cutaneous melanoma: experience of the Genoa group.

AIM: To define the benefit of intraoperative frozen section examination of the sentinel lymph node (sN), and to assess its prognostic value in clinically node-negative melanoma patients. MATERIALS AND METHODS: Between July 1993 and December 2001, 214 patients with Stage I-II cutaneous melanoma underwent sN biopsy; complete follow-up data are available in 169 of 175 patients who underwent preoperative lymphoscintigraphy, lymphatic mapping with Patent Blue-V and radio-guided surgery (RGS). RESULTS: In an initial subset, the sN was identified in 35 out of 39 patients; in the principal group of 169 patients, the sN was detected in all patients. The benefit of frozen section examination, that is the proportion of all patients having intraoperative histologic examination who tested positive, was 17.2% (29/169); notably, in patients with pT(1-2) vs pT(3-4) melanoma the corresponding values were 2.3 and 33.3%, respectively, (P=0.000). Cox regression analysis for overall survival indicated that sN-positive patients had a two-fold increased risk of death; the most significant predictors of relapse-free survival were sN status (P=0.004), age (P=0.015), and T stage grouping (P=0.033). CONCLUSIONS: The sN is a reliable predictor of regional lymph node status in patients with cutaneous melanoma. Frozen section examination can be useful in avoiding a 'two-stage' operative procedure in patients with tumour-positive sN, but its greatest benefit seems to be restricted to patients with pT(3)-pT(4) primary melanoma.

Clinical applications of sentinel lymph-node biopsy for the staging and treatment of solid neoplasms.

A review of the clinical applications of sentinel lymph node (sN) biopsy has been performed with the aim of defining the rationale, the methods of detection, the accuracy, and the current indications to sN biopsy in different solid neoplasms. In melanoma patients, sN biopsy represents a standard procedure for staging purpose, although its therapeutic value is still under examination. The sN is an accurate method for the pathologic staging of the axilla in patients with early stage breast cancer, and it can be useful for the selection of patients with axillary metastasis who should undergo standard axillary dissection. In gynecologic malignancies, appreciable results are available in patients with vulvar and cervical cancer only. Patients with squamous cell vulvar cancer may benefit by sN biopsy because a complete bilateral inguino-femoral lymph-node dissection may be avoided whenever the sN is free of metastasis. As regards to cervical cancer, further studies are required with the combined technique (blue dye injection and gamma-probe guided surgery), which seems more promising, before abandoning pelvic lymphadenectomy in patients with histologically-negative sN. The experience in urologic cancer deals mainly with penile and prostate cancer; the modern procedures for the dynamic detection of sN are going to clarify its role in the surgical management of penile cancer; as regards to prostate cancer, very preliminary results suggest that the sN biopsy may enhance the pathologic staging of this neoplasm compared to modified pelvic lymphadenectomy, due to the individual variability of the lymphatic drainage of this cancer. In patients with clinically node-negative squamous head and neck cancer, the reliability of sN-guided neck lymph node dissection seems promising. The sN biopsy is also technically feasible in patients with differentiated thyroid cancer; however, the future role of this procedure in the clinical decision-making of these patients remains to be defined due to the questionable biological meaning of nodal metastases. Patients with non-small-cell lung cancer should be investigated by means of radiotracers injected at the time of thoracotomy or under CT-scan guidance in order to achieve a satisfactory identification rate (over 80%); the focused histopathologic staging of the sN improves current pathologic staging by conventional bi-valve assessment of all the lymph nodes of the surgical specimen; moreover, the prognostic role of isolated N2 metastasis can be better elucidated. In patients with gastrointestinal malignancies, the intraoperative lymphatic mapping with sN biopsy have suggested that the lymphatic drainage of the gastrointestinal tract is much more complicated than other sites, skip metastasis being rather frequent. In patients with gastric cancer, current data show that it can be detected by means of peritumoral injection of indocyanine green; the detection of tumor positive lymph nodes beyond the perigastric area could select patients amenable to D2 lymphadenectomy. As regards to colorectal cancer patients, the focused analysis of the sN may reveal disease that might otherwise go undetected by conventional surgical and pathological methods, and those patients which are upstaged can benefit by adjuvant chemotherapy. Finally, in patients with Merkel cell carcinoma, notwithstanding the limited experiences with sN biopsy, sN histology seems to predict regional lymph node status and may aid in selecting which patients are amenable to therapeutic lymph node dissection.

Technical issues and pathologic implications of sentinel lymph node biopsy in early-stage breast cancer patients.

BACKGROUND AND OBJECTIVES: Recent studies have demonstrated that the sentinel lymph node (sN) can be considered a reliable predictor of axillary lymph node status in breast cancer patients. However, some important issues, such as optimization of the technique for the intraoperative identification of the sN, and the clinical implications of sN metastasis as regards the surgical management of the axilla still require further elucidation. The objectives of this study was to assess (1) the feasibility of sN identification with a combined approach (vital blue dye lymphatic mapping and radioguided surgery, RGS) and the specific contribution of either techniques to the detection of the sN, and (2) the correlation between the size of sN metastasis (micrometastasis < or = 2 mm; macrometastasis > 2), primary tumour size, and the status of nonsentinel nodes (nsN) in the axilla. METHODS: Between October of 1997 and December of 1999, 212 patients with breast cancer (average age: 61 years; range, 40-79 years) underwent sN biopsy before performing standard axillary dissection. In a subset of 153 patients, both vital blue dye (Patent Blue-V) lymphatic mapping and RGS were used to identify the sN, and the relative contribution of each of the two techniques was assessed. RESULTS: Overall, the sN was identified in 206 of 212 patients (97.1%); at histologic examination of all dissected nodes, 77 of 206 patients had positive nodes (37.3%). The false-negative rate was 6.5% (5/77), the negative predictive value was 96.3% (129/134), and accuracy was 97.6% (201/206). Among 72 patients with positive sN, micrometastases were detected in 21 cases and macrometastases in 51. When micrometastases only were observed, the sN was the exclusive site of nodal metastasis in 17 of 21 cases (80.9%); in the remaining 4 cases (19.1%), nsN metastases were detected in 3 of 14 pT1c patients (21.5%), and 1 of 5 pT2 patients (20%). Macrometastases were detected in patients with tumors classified as pT1b or larger: the sN was the exclusive site of metastasis in 3 of 4 pT1b patients (75%), in 14 of 29 pT1c patients (48.2%), and in 3 of 18 pT2 patients (16.6%). The specific contribution of the two different techniques used in the identification of the sN was evaluated; the detection rate was 73.8% (113 of 153) with Patent Blue-V alone, 94.1% (144 of 153) with RGS alone, and 98.7% (151 of 153) with Patent Blue-V combined with RGS (P < 0.001). Noteworthy, whenever the sN was identified, the prediction of axillary lymph node status was remarkably similar (93-95% sensitivity; 100% specificity; 95-97% negative predictive value, and 97-98% accuracy) with each of the three procedures (Patent Blue-V alone, RGS alone, or combined Patent Blue-V and RGS). CONCLUSIONS: Sentinel lymphadenectomy can better be accomplished when both procedures (lymphatic mapping with vital blue dye and RGS) are used, due to the significantly higher sN detection rate, although the prediction of axillary lymph node status remains remarkably similar with each one of the methods assessed. That patients with small tumours (<1 cm) and sN micrometastasis are very unlikely to harbour metastasis in nsN should be considered when planning randomised clinical trials aimed at defining the effectiveness of sN guided-axillary dissection.

Sentinel lymph node mapping in early-stage breast cancer: technical issues and results with vital blue dye mapping and radioguided surgery.

BACKGROUND AND OBJECTIVES: Axillary lymph node status is the most important prognostic factor in patients with operable breast cancer. Recent studies have demonstrated the possibility of identifying the sentinel lymph node (sN) as a reliable predictor of axillary lymph node status in both cutaneous melanoma and breast cancer. Sentinel lymph node identification proved feasible by either peritumoral dye injection (Patent Blue-V) or radiodetection, with identification rates of 65-97% and 92-98%, respectively. However, some important issues need further definition, namely (a) optimization of the technique for intraoperative detection of the sN, (b) predictive value of the sN with regard to axillary lymph node status, and (c) reliability of intraoperative histology of the sN. We reviewed our experience in sN detection in patients with stage I-II breast cancer to assess the feasibility and accuracy of lymphatic mapping, by vital blue dye or radioguided surgery, and sN histology as a predictor of axillary lymph node status. METHODS: Two groups of patients (55 and 48) were recruited between May 1996 and May 1997 and between October 1997 and February 1998; the patients of the first series underwent vital blue dye lymphatic mapping only, whereas those of the second series had a combined approach with both vital blue dye mapping and radioguided detection of the sN. RESULTS: In the first set of patients, the sN was identified in 36/55 patients (65.4%); sN histology predicted axillary lymph node status with a 77% sensitivity (10/13), a 100% specificity (23/23), an 88.5% negative predictive value (23/26), and an overall 91.5% accuracy (33/36). The sN was the quasi-elective site of lymph node metastases because in clinically N0 patients nodal involvement was 20-fold more likely at histology in sN than in non-sN (30% and 1.5%, respectively). In the second set of patients, 49 lymphadenectomies were performed because 1 patient had bilateral breast cancer; the sN was identified in 45/49 lymphadenectomies (92%). The sN was intraoperatively negative at frozen-section examination in 33 cases, and final histology confirmed the absence of metastases in 31/33 cases (94%), whereas in 2 cases (6%) micrometastases only were detected. Final histology of the sN predicted axillary lymph node status with an 87.5% sensitivity (14/16), a 100% specificity (29/29), a 93.5% negative predictive value (29/31), and an overall 95.5% accuracy (43/45). CONCLUSIONS: Sentinel lymphadenectomy can be better accomplished when both mapping techniques (vital blue dye and radioguided surgery) are used. In this group of patients, agreement of intraoperative histology of the sN with the final diagnosis was 94%, and sN histology accurately predicted axillary lymph node status in 43/45 lymphadenectomy specimens (95.5%) in which an sN was identified.

Pattern of lymphatic drainage to the sentinel lymph node in breast cancer patients.

BACKGROUND AND OBJECTIVE: We performed a pilot study on 30 consecutive patients undergoing sentinel node (sN) biopsy by radioguided surgery and vital blue dye mapping to determine whether there is a single sN for each breast independent of tumor site or an sN specifically related to the site of the breast neoplasm. METHODS: There were 6 groups of 5 patients; each patient had a subdermal injection of radiotracer on the tumor site plus a second injection of radiotracer that was changed in every subset of patients to test whether modifying the site or the route of injection could have impaired the proper detection of the sN. RESULTS: "False" sN were detected only in patients who had a second injection of radiotracer away from the tumor site; this occurred in 2 of 5 patients (40%) in group I, in 3 of 5 patients (60%) in group II, in all patients in group III, and in 3 of 5 patients (60%) in group IV. The different route of injection (peritumoral or subdermal) always on the tumor site that was tested in groups V and VI did not impair the proper detection of the sN. CONCLUSIONS: Our findings support the hypothesis of a precise topographic correspondence between the primary tumor and its specific sN more than the existence of a first sN in the axillary basin, which indiscriminately drains all quadrants of the breast, like "a neck of a bottle." This should be considered for the proper selection of the injection site of either vital blue dye or radiopharmaceuticals.

Preliminary analysis of a randomized clinical trial of adjuvant postoperative RT vs. postoperative RT plus 5-FU and levamisole in patients with TNM stage II-III resectable rectal cancer.

OBJECTIVES: Two-hundred eighteen patients with TNM stage II-III resectable rectal cancer, enrolled into a randomized clinical trial, were assessed for efficacy and toxicity of adjuvant postoperative radiation therapy (RT) vs. those of combined RT and chemotherapy (CT), with 5-fluorouracil (5-FU) plus levamisole. End points were overall survival, disease-free survival, the rate of loco-regional recurrence, and treatment-related toxicity. METHODS: Patients in arm I underwent RT (50 Gy) in daily fractions of 2 Gy, 5 days/week for 5 weeks. Patients in arm II began with 5-FU (450 mg/m(2)/day intravenous bolus, days 1-5) plus levamisole (150 mg/day orally, days 1-3); postoperative RT was delivered during week 2 at the same dosage and schedule as in arm I. The other five cycles of CT (5-FU every 28 days and levamisole every 15 days for the length of 5-FU administration) continued after the end of RT if clinical and hemato-biochemical parameters were normal. RESULTS: RT was completed or modified in 170 (90%) of 189 evaluable patients undergoing RT (both treatment groups). Only 44 (59%) of 75 evaluable patients of arm II completed or had an adjustment of the CT schedule; the remaining 31 patients (41%) had to stop or never started the CT regimen. Patients undergoing combined RT and CT had more severe toxicity (enteritis, P = 0.03). There was one CT-related death (gastrointestinal bleeding) in this subset. No significant difference was observed in outcome of patients in the two study groups, nor for pattern of recurrence (heterogeneity chi(2) = 4.82; d.f. = 2; P = 0.08). CONCLUSIONS: These preliminary findings suggest a similar efficacy, coupled with less morbidity, of postoperative RT alone compared with a combined regimen of postoperative RT and CT in patients undergoing radical surgery for stage II-III rectal cancer.

Mapping sentinel lymph node in breast cancer by combined lymphoscintigraphy, blue-dye, and intraoperative gamma-probe.

The purpose of the present work was two-fold: 1) to evaluate the predictive value of the sentinel lymph node (sLN) versus the axillary-node status in patients with T1-T2 breast cancer, and 2) to form an experimental basis for a randomized trial in which one group of patients with non-metastatic sLN will not have axillary dissection. Of a group of 284 patients considered for this analysis, 264 had a T1 cancer (16 T1a, 37 T1b and 211 T1c), while 20 had a T2 cancer; 243 patients were in clinical stage N0 and 41 were N1. All patients underwent lymphoscintigraphy 18 hr before surgery: 10 MBq in 0.15 mL of 99mTc-human albumin nanocolloids (particle size between 50-80 nm) was injected subdermally at the cutaneous projection of the tumor. Static gamma-camera images were acquired every 10-15 minutes until scintigraphic identification of the sLN. At surgery, 1-2 mL of Patent-Blue Violet was injected subdermally, and the sLN was searched by gamma-probe and by the dye method. The surgically isolated sLN was processed for intraoperative Hematoxylin & Eosin (H&E) histology, then for delayed histological and immunohistochemical examinations. The sLN was successfully identified by the combined radioisotopic procedure and Patent-Blue dye technique in 278/284 cases (97.9%). The Patent-Blue dye technique alone identified fewer sLNs than the radioisotopic procedure alone (56.3% versus 97.2%). Analysis of the predictive value of the sLN as to the status of axillary lymph nodes was limited to 197 patients undergoing standard axillary dissection irrespective of the sLN status. Overall, 63/191 (33%) identified sLNs were metastatic, the sLN alone being involved in 37/63 (58.7%) patients; a positive axilla status with negative sLN was found in 10/73 patients with metastatic involvement (13.7% false-negative rate). In conclusion, subdermal lymphoscintigraphy was confirmed to be an effective technique for sLN mapping; the addition of Patent-Blue dye minimally improved intra-surgical identification of the sLN. There was a high, but not absolute, correlation between a negative sLN and a negative axilla.

Radioimmunoguided surgery with different iodine-125 radiolabeled monoclonal antibodies in recurrent colorectal cancer.

Sixty-four patients with recurrent or metastatic colorectal cancer underwent radioimmunoguided surgery (RIGS). Thirty patients (Group A) were preoperatively injected with radiolabeled monoclonal antibody (MAb) B72.3, a whole IgG1 that reacts with tumor-associated glycoprotein (TAG-72) antigen. Thirty-four patients (Group B) were given monoclonal antibody FO23C5, an F(ab')2 which reacts with the carcinoembryonic antigen (CEA). The use of F(ab')2 antibodies ensured a lower time interval from the preoperative injection of the radiolabeled MAb to surgery. This interval was 22.7 days for Group A patients and 10.9 days for Group B patients. The correct RIGS identification of tumor sites occurred in 80.4% of Group A patients and in 92.6% of Group B patients. Additional information capable of modifying surgical strategy was obtained in 23.3% of Group A patients and in 8.8% of Group B patients. This difference was due to the different patterns of biodistribution and pharmacokinetics of the two MAbs. Although FO23C5 yields an improved diagnostic resolution for macroscopic tumor sites, we believe that B72.3 or other whole IgG1 should be the first choice for RIGS in recurrent or metastatic colorectal cancer patients.

Sentinel lymph node mapping opens a new perspective in the surgical management of early-stage breast cancer: a combined approach with vital blue dye lymphatic mapping and radioguided surgery.

Recent studies have demonstrated the possibility of identifying the sentinel lymph node (sN) as a reliable predictor of axillary lymph node status in both cutaneous melanoma and breast cancer. However, some important issues need further definition: (1) optimization of the technique for intraoperative detection of the sN; (2) predictive value of the sN as regards axillary lymph node status, and (3) reliability of intraoperative histology of the sN. We report our experience in sN mapping in patients with Stage I-II breast cancer, with the aim of assessing: (1) the feasibility of lymphatic mapping with a combined approach (vital blue dye lymphatic mapping and radioguided surgery); (2) the agreement of the intraoperative histologic examination of the sN, by means of hematoxylin and eosin staining with final histology, and (3) the accuracy of sN histology as a predictor of axillary lymph node status.

Sentinel node biopsy in patients with cutaneous melanoma.

The role of elective lymph node dissection (ELND) for treatment of cutaneous melanoma is still debated. Initially, lymphatic mapping technique was performed by an intradermic injection of vital blue dye; subsequently, it was improved by the use of radioguided surgery (RGS). Preliminary experience with this technique proved effective for detection of clinical occult lymph node metastasis; it may also enable the surgeon to perform a selective lymph node dissection (SLND) to concentrate on pathologic node-positive patients for the same potential benefits that have been provided by ELND. We performed sentinel node biopsy on 48 patients with stage pT3N0M0 melanoma. Vital blue dye mapping only was carried out on 39 patients; the remaining nine patients had a combined lymphatic mapping with both blue dye and RGS. The sentinel lymph node (SLN) was identified in 46 of 48 patients (95.8%). Ten patients (20.8%) were found to have metastatic melanoma cells in their SLN(s); all these patients underwent SLND of the affected basin. Our findings confirm that the intraoperative lymphatic mapping of the SLN using both blue dye and radiodetection is an appropriate and simple technique for selecting patients who are more likely to benefit from lymph node dissection.

Prognostic role of lymph-node level involvement in patients undergoing axillary dissection for breast cancer.

AIMS: Clinical records of patients undergoing surgery for breast cancer were reviewed in order to evaluate the prognostic role of lymph-node level involvement. METHODS: From 1982 to 1991, 1143 patients had radical mastectomy or conservative surgery with total axillary dissection: 461 patients of mean age 57.1 years (range: 25-89 years) were lymph-node positive (pN1); 369 patients (80%) had radical mastectomy; and 92 patients (20%) had conservative treatment plus post-operative radiotherapy, with the same mean number (n = 16) of lymph nodes collected in the surgical specimen. Data were analysed for the number of positive lymph nodes and level of involvement. RESULTS: Level I, Levels I + II and Levels I + II + III were involved in 44.9, 18 and 21.4% of patients, respectively; 'skip metastases' occurred in 72 of 461 pN1 patients (15.5%). A univariate analysis showed that prognosis was directly related to the number of levels involved (P < 0.001), and skip metastases had the same prognostic role as Level I involvement. The numbers of involved lymph-node levels and metastatic lymph nodes were well correlated; multivariate analysis showed that involvement of Levels I and III was independently correlated with prognosis. After adjustment for age and number of positive lymph nodes, the number of involved lymph-node levels was an independent prognostic factor, with highest predictability when all three lymph-node levels were positive (P = 0.009). CONCLUSIONS: The prognostic value of lymph-node status should be defined not only by the number of metastatic lymph nodes, but also by the number of levels of involvement.

Surgical complications related to peri-operative adjuvant chemotherapy in breast cancer. Results of a prospective, controlled, randomized clinical trial.

From May 1985 to June 1992, 375 patients were enrolled in a prospective controlled randomized clinical trial of peri-operative adjuvant chemotherapy (PAC) associated with long-term adjuvant chemo-endocrinotherapy in order to test the effectiveness of reducing the time interval between surgery and chemotherapy. The short-term surgical complications related to PAC are reported in order to verify whether such treatment might negatively affect the results of breast cancer surgery. One hundred and eighty-nine patients were randomly assigned to the peri-operative treatment, and 186 to the control group. Patients undergoing PAC received one course of cyclophosphamide (600 mg/sqm), epidoxorubicin (60 mg/ sqm), and 5-fluorouracil (600 mg/sqm) (CEF) within 48-72 h following surgery. Pathologically node-positive (N+) patients, who were given peri-operative CEF, had five further cycles of CEF alternated with six cycles of CMF (cyclophosphamide 600 mg/sqm, methotrexate 40 mg/sqm, and 5-fluorouracil 600 mg/sqm). All the other N+ patients received six cycles of CEF alternated with six cycles of CMF, starting within 30 days of surgery. No significant difference in post-operative morbidity was observed as regards median hospital stay (8 days), number of outpatient dressings (3.5 vs 3), seroma (51 (26.9%) vs 45 (24.2%)), lymphatic drainage (400 ml vs 409 ml), and post-operative infections, both local (10 vs 9) and in extraoperative foci (6 vs 7), in the study and control group, respectively. The toxicity of the peri-operative CEF was mainly gastrointestinal (nausea and vomiting, 55%; stomatitis, 3%), with only a small percentage (9%) reaching grades III-IV. Hair loss was the other main side effect (55%) with baldness in only 3%. Post-operative complications following radical breast cancer surgery seem to be primarily related to operative details (type of incision, accurate nerve-sparing technique, bleeding control, closure of subcutaneous and skin, drainage, aseptic technique) rather than to the one course of PAC.

Phase II study of vinorelbine and ifosfamide in anthracycline resistant metastatic breast cancer.

The new combination of ifosfamide and vinorelbine was evaluated in a phase II study of patients with metastatic breast cancer. All the patients had evaluable or measurable lesions resistant to the combination of cyclophosphamide, epidoxorubicin and 5-fluorouracil. Out of 25 patients entered the trial, 7 achieved an objective response (28%) (95% C.I. 12-49.3). Ten patients (40%) experienced stable disease and the remaining patients (30%) progressive disease. The median time to progression was 4 months (range 2-12+). The activity of the ifosfamide-vinorelbine combination has been demonstrated and the toxicity was acceptable.

[The surgery of breast carcinoma. 10 years of activity].

From 1981 to 1990, 1003 stage I-II breast cancers underwent surgery at the Division of Surgical Oncology of National Institute for Cancer Research of Genoa. This study described the clinical and pathologic features of these breast cancers. Radical mastectomy was performed in 73.8% of cases and conservative surgery in 26.2% of cases. In the last years the number of conservative treatment has increased. Related to size of tumour, in 1991 80.4% of pT1 performed a conservative surgery. The choice of type of surgery for pT2 tumours depended on the choice of patient and the ratio breast size and tumour size. The five-year overall survival was 85.8% in the group of conservative surgery and 65.3% in the group of radical surgery. The overall survival and relapse free survival have been calculated by Kaplan-Meyer method. Actuarial survival curves were computed according to type of surgery, tumor size, nodal status, hormonal receptors. In our experience the size of tumour was an important prognostic factor. The five years, overall survival was 80.7% in pT1 tumours and 67% in pT2-pT3 tumours (p = 10(-6)). The five-year overall survival in negative nodes patients was 80.5%. Conversely in patients with more than ten nodal metastases was 29.5%. The data reported in the present study were no different as in previous studies.

Radiation-associated angiosarcoma: diagnostic and therapeutic implications--two case reports and a review of the literature.

BACKGROUND: Angiosarcoma (AS) accounts for 1 to 2% of all soft tissue sarcoma. Both primary and secondary AS may occur, the latter being reported in the upper extremity with lymphedema after extended radical mastectomy for breast cancer (postmastectomy AS) or following radiotherapy of the breast, the thoracic wall, or other sites (radiation-associated AS). The authors report two cases of cutaneous radiation-associated AS and review literature regarding treatment planning and follow-up data to define the most appropriate therapy for cutaneous and noncutaneous radiation-associated AS. METHODS: The clinical records of two patients with radiation-associated AS were analyzed and previously reported cases were reviewed. RESULTS: Case 1: a female age 67 years developed cutaneous AS in the residual breast 27 months after breast-conserving therapy and conventional external beam radiotherapy (EBR). She underwent chemotherapy followed by simple mastectomy and chemotherapy with the same regimen but developed early recurrence that was treated with hyperthermia and EBR, wide excision, and second-line chemotherapy. She died 30 months after primary diagnosis of AS with multiple metastases. Case 2: a male age 59 years developed cutaneous AS in the left groin, 10 years after conservative surgery and EBR for a penile carcinoma. Early recurrence following wide excision was treated with chemotherapy, re-excision, and immunochemotherapy but the patient died 24 months after the primary diagnosis of cutaneous AS with local progression and distant metastases. CONCLUSIONS: The prognosis of radiation-associated AS is dismal, due mostly to its poor differentiation and frequent diagnostic delay. Simple mastectomy is advised for patients with cutaneous AS after breast-conserving surgery with wide tumor-free margins. If primary surgery fails, survival is seriously compromised because adjuvant or palliative treatments are not effective.
